"Apphcation filed April 16, 1913. Serial No; 761,578.

'0 all whom it may (IO'TLCGTILI Be it known that I, Enwix R. PROBERT, a

citizen of the'llnited States of America, and.

a resident of- Covingto1 i-, in the countyof Kenton and State of ixentucky, have invented a certain" new anduseiful Improve i'nent in Sheet-Metal Roofing, of which the following 12; a specification.

This invention; relates to sheet-metal roofing that has an elevated lock-joint and;

is secured to the sheathing belowbyaneans of concealed nails or the like.

The object of this invention is to provide an extremely simple, elevated, oint for the edges of contiguous sheets.

All the featuresoi'the invention hereinf' will be minutely described hereinafter and particularly pointed out in the clamp In the accompanying sheet of drawings, Figure 1 is a fragmentary isometric view showing my improved interlocked joint 3- Fig. 2, an end elevation otthe joint seen in- Fig. 1 tion so as to to view the peculiar manner of making the joint andassociating or assembling its parts; Fig. 3, an end elevation of a modified form of the joint inwhich the hooking ,recessor groove is made horizontal instead of at an inclination as shown in the first two views; Fig. at, a fragmentary end view of one jointcdge of a sheet; and Fig. 5, afragmentary end view of the other joint-edge of a sheet,

but without the perspective projecthe formation being the same as that seen in Figs. 1 and 2.

1 indicates the base or body portion of one of the roofing sheets and 2 the base or body portion of the contiguous roofing sheet, the latter being the first one laid onthe sheath ing and the former 3 indicates an upwardly slanting flange or limb made along one edge of the, sheet 1';

&

interlocked bring moreclearly and squarely duly interlocked in the manner that I shall now describe,

joint, although 3-fo'rm composed o f the membersS, 9 and 10, such members 8, 9 and 10 being preferablv, at an inclination of ten degrees-more orfless from the'plane of the sheets 1 and 2, as best seen inlhgoiZ, so that when the oint is effected, with the hook-formation of the sheetl in: due engagement;therewith, the inner edgeo'l the lowerhook-member 5 conalso, so that the extreme upper edge of said upper member 10 shall impinge against the under-s1 de of thebend in the metal made be} tween the members 3 and 41 of the sheet 1.

The said impingements or contacts of the hook-formation on the sheet 1 and the S foi' mation on the sheet 2 effectually prevent the entrance of any moisture or water into the joint as each impingement forms a suitable barrier in the joint beyond which said moisture or water cannot pass into the sheathing beneath the sheets. The upper end of theS-formation has an extension 11 at an inclination downwardly to correspond to the inclination of the member 3 of the sheet 1,under which it lies in contact, and the lower end of the extension 11 still further extends, into a horizontal footor flanges 12 that receives the fastening-nails 18, one of the latter being shown in position, concealed beneath the sheet 1. r

The sheet 1 is very readily connected with the sheet 2 by simply inserting the inner edge of the lower member 5 of the hookformation in the lower loop or opening of the S-formation. In making the coupling or joint between the two sheets the sheet 1 need not be inclined verv materially so that the inner edge of the hook shall engage the lower loopof the S-formation' and, when the body portion of said sheet 1 is set or laid in place on the sheathing, the locking of the'joint is fully made and effected in a most simple and easy manner.

In Fig. 3 I have shown the s-formation as being composed of members 8 and 9 that arehorizontal instead of slanting, and the upper member 10 has less slant than the degree of inclination of the same member shown in Fig. '2, but it is not as effective a structure against the inward seepage of "moisture or water that is running over the elevated above the plane of the sheet 2, because there is not the same impingements or contacts of the lower. mem
